We have previously demonstrated that F. graminearum can utilize SA as sole source of carbon to grow. In this current study, we selected four fungal SA-responsive genes that are predicted to encode salicylic acid (SA)-degrading enzymes and we used a gene replacement approach to characterize them further. These included two genes predicted to ...

Limited information existed on its potential impact on swallow-worts, and the combination of defoliation damage by A. asclepiadis and other stresses to the plants had not been studied. We conducted greenhouse studies...

Rosset, Plantard G., Djessas K.AbstractSolar applications in the treatment of waste water fields were limited by the fact that the photocatalytic efficiency of photoreactors, and specifically the photocatalyst used, was less than one percent. Here we report a study investigating the catalysts based on Zn1-xMxO compounds for different [M]/[Zn] atomic ratios. M elements: Na, K, Li, Fe, V, Co, Mg, Mn, Ca, In, Al, P, Ce, were selected. All these catalysts were synthesized by sol-gel process. The morphological, ...

To cope with the increased demand for these therapeutics, more productive manufacturing processes have been developed using high-density cultures and enriched feeds/media. This has dramatically increased the productivity of mammalian cells in culture but this is accompanied by an increased production and accumulation of lactate in cultures, with the pattern of phasic produc...

Hence, searching for an efficiently heterogeneous catalyst with high stability and dispersion is one of the important targets of chemical technology. Here, we report a Ba-K/Ru-MC catalyst with Ru particle size of 1.5–2.5 nm semi-embedded in a mesoporous C matrix and with dual promoters of Ba and K that exhibits...

Herein, we report the deposition of CuO and Au nanodomains on Cu2O cubes to form dual surface heterostructures (HCs) to improve photocatalytic activity and stability. The apparent quantum efficiency of Au/CuO/Cu2O HCs was ca. 123 times that of pristine Cu2O. In addition, the Au/CuO/Cu2O HCs maintained nearly 80% of its original activity after eight cycles i...
